Hello Mervyn,
 BB> Anyone want to share a screen clearing routine?
 JV> This only works properly in the Northern Hemisphere.
 MB> I'm up there and couldn't get it to go in a translation for A86.
     I did :-)
     ...(fade.asm that you posted)...
     You implied that this bat will restore the screen?
 MB> I have a BAT file I use often
 MB> @echo off
 MB> mode con: lines=43
 MB> mode con: rate=32 delay=1
     This did not restore the screen after running the fade.
     I added some code to detect a keypress, clear it, and
     invoke a mode3 screen. Then your batch would set 43 lines.
     Also removed all the delay loops!
     They did nothing, here (ET-4000 isa vga card).
     I would rather fade up the screen.
     Here is the A86 format code.

     I would like it, though I think it will only inc the loop
     instead of "decing" it.
Kind regards, Barry
